I have a 722k w/ the optional OTA module. While this doesn't always happen, it does occur most of the time and it's a bit annoying. When I switch from a SAT channel to OTA, I get an unstable (yellow "no signal" warning message blinks off/on) OTA signal for about 10 and sometimes for as long as 15 seconds. Then it appears that the signal "stabilizes" and all is okay. If I'm already on an OTA channel and switch to another OTA channel, this does NOT happen -- nor does it happen when going from OTA to SAT. Is this issue normal, or do I have a defective OTA module? Is it possible the module is not firmly "seated"? It is secured by 2 screws which are snug. Thanks!
